Site constraints 4

St. Fagans conservation area
Demolition needs planning permission and permitted development is restricted.
The council must give weight to preserving or enhancing the area's character and appearance. Not every council has published its boundaries as open data.
Registered park or garden 88 m away: St. Fagans Castle
Its setting is a consideration for work nearby.
Registered parks and gardens, battlefields, world heritage sites and protected wrecks are designated heritage assets: harm needs clear and convincing justification.
Also on the record
13 listed buildings within 150 m; Radon affected area, class 4.
Not affected
Outside flood zones 2 and 3 · No scheduled monument at the site

Checked on 6 October 2026.

A boundary can run through a site and the council holds the definitive record: confirm with the council before relying on this.
